CHARLES MILLS, OF NEWTON, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO SACO-PETTEE COMPANY, OF NEWTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

MACHINE FOR ATTACHING CLOTHING TO FLATS.

Application filed November 12, 1909.

To all whom it may concern:

Be it known that 1, CHARLES MILLS, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Machines for Attach- -ing Clothing to Flats, of which the following is a specification.

The attaching of clothing to flats has been accomplished by machinery which is large, expensive to build, and not easily portable, so that it usually forms part of the machine builders plant. As a result when it is necessary to replace the clothing on flats they must be sent from the mill to the builder.

My invention comprises a simplified ma chine which is comparatively small, is quite portable, may be constructed at comparatively small expense, and is fitted to be part of the equipment of any mill in which flats are used. Moreover it is easily operated so that by means of it the clothing on flats may be replaced by any good mechanic. In the drawings the preferred embodiment of my machine is shown.

Figure 1 is a side elevation of a portion of a machine embodying my invention. Fig. 2 is a cross section on line 22 of Fig. 1, showing the machine in position to begin its operations. Fig. 3 is a similar section showing the jaws in the act of attaching the clothing' Fig. l is a longitudinal section on line 4% of Fig. 2, and Fig. 5 is a plan, the jaws being open, the machine being ready to receive the work.

It will be understood that the machine in question may be made of any desired length according to the length of the flats and that certain of the parts shown will be as long as are necessary, the cams and other operating parts being duplicated along the ma chine as occasion may require. Upon the base A are mounted uprights B at convenient distances apart, such as to give the necessary support to the moving parts.

0 is a cam shaft which is supported in suitable bearings I) in the uprights B. This shaft runs the length of the machine and is rotated by power applied through a pulley or gear (not shown) or by hand through a crank handle, as may seem best. Keyed to this shaft (see Figs. 2 and 3) are two cam D, E, which are set opposite to each Specification of Letters Patent.

other, the same key preferably serving both cams. to fill the space between the bearings b to two successive uprights. Against these cams lie the lower ends of levers D E which are pivoted for oscillatory movement upon the fulcrum studs D E These studs also run the length of the machine and the bearing D E of each lever is sufliciently wide to lie between the bearings b of the adjacent uprights B so as to prevent lateral play.

The upper arm of each lever is comparatively short and each carries a jaw 03, 6, these jaws being sufliciently long to form with the next jaws in line a continuous attaching mechanism (see Fig. 5 where the middle jaw is shown in full and fragments of the adjacent jaws are also shown). Each jaw (Z, c has a substantially rectangular groove in its lower front edge, the working surfaces or dies of which are indicated at (Z d 6 6 the exact shape of the groove depending somewhat upon the shape of the edge of the flat with which it is to cooperate. The face 6Z3, 6 of each projects forward sufiiciently to cooperate in the attaching operation by pushing the outer portion of the metallic edge of the clothing down toward the surface of the flat as the jaw moyes toward the flat, thus stretching the clothing and drawing it around the edge of the flat until the groove reaches a clamping position to clamp the clothing against the flat.

The flat is lettered F and the fasteners or metallic edges of the clothing f. G is the table mounted on the uprights B on which the clothing and flat are supported during the covering operation. For this purpose the table is provided with a longitudinal recess g of suflicient width and depth to allow the teeth f of the clothing to hang down into it. The rim g at each side of the recess is suificiently wide and strong to furnish a firm support for the flat and clothing during the covering operation. The table thus cooperates with the jaws in applying the clothing.

The operation of this machine is simple. The clothing is laid on the table G with its teeth f projecting into the recess 9. It is properly centered and the flat F laid upon it, the metallic edges f of the clothing standing upright as shown in Fig. 2. The shaft They have hubs of sufficient width C is then turned and moves the cams D, E from their position in Fig. 2 to the position in Fig. 8. This action separates the lower ends of the levers D E and brings the jaws .d, 6 toward each other, so that the faces d dies (Z (Z 6 6 as shown in Fig. 3 to set he same. The cams then release the levers and they fall back to their first position because of their shape and weight. The cams are set opposite each other and are preferably keyed together as well as to the cam shaft, and the dies are set in the same position the entire length of the machine so as to act simultaneously upon the clothing.

The simplicity of this machine is apparent and it is evident that the dies may be dif ferently shaped according to the shape of the surface of the flat which they are to engage and may be difierently mounted and operated if thought best. The embodiment of the invention shown however has proved satisfactory both from the point of view of construction and that of operation. The moving parts are well supported and the construction lends itself to the setting up of machines of different lengths with but slight changes.

vVhat I claim as my invention is:

1. In a machine for attaching clothing to flats, in combination, a frame, a table carried thereby, a pair of jaws one pivotally mounted on each side of said table, and means for causing said jaws to approach a flat located on said table to attach clothing thereto, each jaw having a face adapted to engage the upright edge of a fastener and turn it against the horizontal surface of the flat and having a die adapted thereafter to engage said turned edge and clamp it against said flat.

2. In a machine for attaching clothing to flats, in combination, a frame, a table carried thereby and adapted to support a flat and its clothing, a pair of jaws one pivot-ally mounted on each side of said table, and means for causing them to approach said flat simultaneously, each jaw having a face opposing the face of the other jaw and having below said face and adjacent to it'a right angled die, whereby as said jaws approach the unattached clothing 011 a fiat, said clothing having fasteners attached to each edge thereof, the face of each jaw will engage said fasteners simultaneously and press them toward each other and against said flat thereby stretching said clothing about said flat and said dies will simultane ously clamp said fasteners about said fiat, as set forth.

3. A machine for attaching clothing to flats, comprising a frame, a table carried thereby to support the flat, a pair of jaws on each side of the table, and means for causing said jaws to approach and stretch the clothing on said flat and thereafter to clamp a fastener on each edge of said clothing to said flat and set the same.

4. A machine for attaching clothing to flats, comprising a frame, a table attached thereto, a pair of jaws on each side of the table, said jaws having fastening-turning and clothingestretching surfaces, and means for causing said aws to approach and stretch said, clothing and thereafter to attach one or more fasteners connected thereto to said flat, whereby the stretched clothing is attached to said flat as set forth.
